From Romeo and Juliet to Napoleon and Josephine, Hollywood never forgets to glorify these exceptional love stories. But, there's one such story, that had remained untold and overlooked for a long time, a real love story that didn't get to meet the public eye until now.

It's the story of a revolutionary storyboard artist and an extraordinary film researcher, whose path collided, creating a huge conversion in American film history.

Often referred as 'secret weapons' or 'power couple" of Hollywood, their wonderful love story has finally reached the screens, with the effort of the famous documentary director, Daniel Raim; a huge tribute to this wonderful couple.

But before talking about the movie, let's take a moment to know the amazing love story of late Harold Michelson and his wife Lilian Michelson.        

Hollywood's greatest love story of Harold and Lilian Michelson

The late Harold Michelson, who worked as an illustrator and storyboard artist for more than five decades was a happily married man.

He met his gorgeous, fun and curious wife, Lilian after WorldWar II in Florida back in 1945. As dramatic as it sounds, both fell in love and eloped to California and started their amazing life together.

The powerhouse couple got married and a new life awaited them. The pair was proud parents of three sons, who have now grown up to be successful men in their respective fields.

Harold started his career in the film industry after the end of World War II and before that he was a bombardier-navigator in the U.S. Air Force.

He dedicated much-doing storyboards for greatest movies of that time including The Ten Commandments, Ben-Hur and Spartacus.

Eventually, he established himself as the industry's best storyboard artist. Lilian who supported and loved her husband dearly found a position at a film research library, first as a volunteer and later as a veteran film researcher.
